"No files" display on Files tab w/ faulty federation shares or External Storage

[Ophrys78]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

A federation share (displayed as a top level folder) went down. On NC 27.1.9, I noticed nothing. After upgrading to 28.0.5, my files were not displayed with a message like "No files" in the NC files tab.

Steps to reproduce

1. A federation share (displayed as a top level folder) goes down.
2. Click on Files tab.
3. No files/folders showing. (And the "+ New" button is greyed with the following message: "You don’t have permission to upload or create files here".)

Expected behavior

Files showing. Maybe a message/pop-up to inform the user that the federation share is unavailable?

Reproduced. Easy enough to do so: in my test bed I took my Minio instance out of service.
